Abstract

The invention discloses a structure for improving the thread bearing capacity by deformation compensation. The structure comprises a fixing seat, a housing, a first bearing, a second bearing and a lock nut. The first bearing and the second bearing are both arranged between the fixing seat and the housing. The lock nut is connected to the end of the fixing seat in a threaded manner. In the axial section of the lock nut, an included angle is formed between the extending direction of an internal thread of the lock nut and the extending direction of an external thread of the fixing seat, and the opening direction of the included angle is toward the outside of the lock nut. According to the structure for improving the thread bearing capacity by deformation compensation, by the adoption of the threaded connection mode of the tapered thread, the axial preloading of the bearings is realized, and the lock nut is deformed under the axial load effect of the bearings for compensation to complete the effective engagement of inner and outer threaded teeth; and the bearing strength of the threads is improved, the bearing performance of the lock nut under the working load is improved, and the locking failure caused by the poor threaded pair engagement state caused by the deformation of the lock nut is avoided effectively.

Description

technical field [0001] The invention relates to the technical field of locking structures of engineering machinery, in particular to a structure for improving the bearing capacity of threads through deformation compensation. Background technique [0002] In construction machinery, the structure of the traveling reducer and the hoisting reducer is basically the same. The fixed seat and the shell are supported by a pair of tapered roller bearings arranged back to back, and the screw thread between a lock nut and the fixed seat Connect to realize the axial locking function of the tapered bearing. [0003] Due to the limitation of the axial size of the reducer, the lock nut is generally large and thin. Under the action of the axial load component of the preload and the working load, the lock nut needs to bear a large axial load, and the lock nut is easy to It presents a bowl-shaped deformation, resulting in uneven contact of the thread teeth, uneven thread loading, weakened loc...
